研究表明臀部力量的增强能够减少膝关节骨性关节炎的疼痛

Varus deformity of the knee 膝盖内翻足畸形

Knee osteoarthritis is characterized by a wearing-down of the cartilage, usually around the end of the femur bone. Depending on the repetitive forces placed on the knee, osteoarthritis may be more predominant in a specific area. One of the most common areas of cartilage damage in knee osteoarthritis is the medial aspect, and is often associated with a varus malalignment deformity.

Researchers have shown that patients with knee osteoarthritis and varus malalignment demonstrate higher knee adduction forces compared to control subjects (Baliunas et al. 2002), and the magnitude of the force is associated with increased knee pain (Schrader et al. 2004). Hip muscle strength has also been implicated as a factor in excessive knee adductor force (Change et al. 2005).

膝关节骨性关节炎是因为软骨的磨损，通常是在大腿骨的周围，由于强加于膝盖的磨损，骨关节炎会变得更加严重。最常见的一个地方是在膝盖关节炎软骨损伤内侧和内翻足错乱排列畸形有关。研究人员证明患者膝部骨关节炎和愈合的膝盖内翻的对照组相比更有力量。（Baliunas et al. 2002)。

力量的大小和膝关节的疼痛时间有关。臀部肌肉力量增强和膝关节收缩用力过多有关(Change et al. 2005).

Australian researchers wanted to know if a hip strengthening program would be beneficial to patients with medial knee osteoarthritis. 89 patients diagnosed with medial knee osteoarthritis were randomly assigned to a hip strengthening group or to a control group. The exercise group completed a 12-week home exercise program targeting hip abductor and adductor strength utilizing ankle weights and elastic bands. (Download the protocol here.) 3-dimensional gait analysis was used to calculate knee adduction forces. The participants were also tested for pain, self-reported function, and muscle strength before and after the 12-week program.

意大利的研究者想知道是否增强臀部力量的计划对膝盖关节炎患者有用。89名有膝盖关节炎的患者被随机分到臀部力量加强组合对照组中去。运动组主要利用赛乐小沙袋和弹力带做髋外展和内收完成了12周在家锻炼项目。三维步态分析被用来计算膝盖内收的力量。经过12周的计划前后，受试者进行了疼痛测试、自测报告和肌肉强度对比。

85% of the participants completed the study. While there was no significant difference in the change of the knee force between groups, all pain, function, and strength measures significantly improved in the exercise group. The authors suggested that hip muscle strengthening does not influence progression of disease, but may reduce its symptoms. Unfortunately, the authors chose primarily open-chain strengthening exercises which might not be appropriate to reduce a dynamic closed-chain force created by the knee adductor moment.

85%的参与者完成了这项研究。在两组人中膝盖肌肉力量没有明显变化，运动组所有的疼痛、功能、加强措施等明显改善了。作者提出加强臀部肌肉不会影响疾病进展，反而会减轻其症状。可惜的是，作者主要选择的开链练习可能不适合于膝关节内收时动态的闭链练习。

In summary, strengthening hip muscles using Thera-Band exercise bands and cuff weights can successfully reduce symptoms of medial knee osteoarthritis

总之，用赛乐弹力带和赛乐小沙袋增强臀部肌肉能够有效减轻内侧膝盖关节炎的症状。

同感！平时对客户训练时针对膝关节问题做过加强臀部肌肉的训练，收效不错！
